Window Trickle Vents

What Are Trickle Vents?

Window Trickle Vents are an easy and effective way to improve the air in your home. These are usually fitted at the top of your window frames and you can open or close them as you like to manage the airflow. They’re especially good for tackling issues like dampness and mould. Plus, they come in a variety of sizes and styles, so you can find one that suits your needs. If you’re considering installing them on existing windows, it’s best to talk to an expert, as this could involve drilling or cutting into the frame.

Stay Up to Date with New Regulations

As of 15 June 2022, new building rules in England require windows to have trickle vents. This applies to both new and existing homes, so it’s essential to make sure you’re following the law.


Pick the Right Vent for Your Home!

MB DIY offers two main types of trickle vents: Standard and High-Flow. Standard vents provide a gentle influx of fresh air, while High-Flow vents allow for more air to come in. These bigger vents may also have features like adjustable louvres to give you more control over airflow. So, how do you decide between them? Think about how much ventilation you need, which can depend on the room size and the number of people in it.

Add Some Colour with Trickle Vents

At MB DIY, you have plenty of choices when it comes to colours. Whether you’re looking for something traditional like white uPVC or something that matches wooden frames, we’ve got you covered. Picking the right colour can make a world of difference in your room’s overall look.

Go Chic with Black Vents

Black vents offer a modern and stylish touch to any room. They work particularly well with black window frames, providing a unified, sleek look. They can also add a striking contrast to lighter frames.

Keep It Classic with White Vents

White vents are versatile and timeless. They blend in easily with any window frame or interior style, making them a popular choice for those who want a subtle look.

Add Warmth with Brown Vents

Brown vents offer a warm and inviting atmosphere to your room. They’re great for complementing wooden frames or offering a contrast to lighter ones. They can even add a natural feel to a room with other earthy elements.

Why Trickle Vents Are a Good Idea & Do They Stop Condensation.

We get asked a lot of questions about trickle vents but one of the main questions asked is “Do Trickle Vents Stop Condensation”… In short, the answer is no however trickle vents are designed to allow a small amount of ‘background’ air circulation. This will assist in reducing condensation, damp and mould inside properties especially around windows as these are normally the coldest place in a room so therefore the first place that condensation will form. Trickle vents are practical. They come in Standard and High-Flow options and in various colours like black, white, and brown. With new building laws now requiring them, it’s crucial to choose the right type for your home’s needs.

Trickle vents are easy to install, improve air quality, and help in reducing issues like mould and dampness. Contact us today to find the trickle vent that best suits you.
